The other way is not bad either. Long as you have a good spring tool, you can remove the springs, unbolt the motor/pump, disconnect the air hose and the whole unit comes right out. Another 5 minutes work.
After you've done it a couple of times, it will be the easier of the repairs done on this product, compared to the triple lip seal and bearing. Use the same Amana spring tool the guy is using below on the Neptune boot. Works great on both!
